Whenever a new Android device hits the stage, we feel obligated to see how it measures up to the latest iPhone. Let's have a look-see.

Both phones have their main I/O connector on the bottom, flanked by two screws. For the iPhone, it's the Lightning connector (Apple proprietary) and two Pentalobe screws (also proprietary). The Nexus 4, on the other hand, wields a micro-USB/SlimPort HDMI port (universal) and two Torx screws (quite common).

Rather than hide the Micro SIM card underneath the battery—a common practice in many phones—LG pushed the Micro SIM slot to the side and included their own stubby SIM eject tool. Very Cupertino.

With the frame screws removed, the Nexus 4 is officially screw-less. That brings us to a total of only 4 different screw lengths, and 15 screws in total. Here's how they break down on our Magnetic Project Mat.

FYI, just replaced my screen assembly and ran into an issue where the proximity sensor is always blocked. After scouring hours unsuccessfully for a solution, a YouTube comment mentioned swapping the orientation of the rubber gasket so that the big hole surrounds the little proximity sensor. That solved it!

Would it be possible to swap the 8gb flash module (or 16gb in the 16gb version) to a 32gb module? I'm guessing the 16gb version would use a Toshiba THGBM5G7A2JBAIM module, which has the same package and power requirements as the THGBM5G8A4JBAIM (32gb module). Could this be as simple as a straight swap? I tried to get a closer look at the IC in your pic on step 17, but the red outline makes it hard to get a good look at the surface mount soldering on the chip. But seeing as you guys have actually seen it, would it be at all possible to make this modification by hand?

One more question: I have been reading that the 7 band LTE chip is useless without the LTE radio. But then in Step 18 it states that there is a 4G GSM/CDMA modem. Isn't this what is needed to make the 4G actually work?

How accessible are the SIM pins with the mobo out? I've bent one and it's nearly impossible to correct the bend through the tiny SIM hole with the case on. But I don't want to rip the entire phone apart and risk breaking it further if I won't gain an advantage in SIM pin access by doing so (I will just continue to try and straighten it out through repetitive "massaging" :)

How accessible are the SIM pins with the motherboard out? I have a bent one, but don't want to tear the whole phone apart if it doesn't give me an advantage in re-shaping the bent pin by doing so. Help!

Linear Resonant Actuator: Would it be possible to get part information on the LRA and the driver for it? This actuator is extremely mild, in fact so much so that it is useless as a ringer substitute in my pocket. I would like to see if there might be any drop in replacements for it

Easiest way to take of the front screen: start at the simcard slot, and make sure the tool is snugly in place, then slide it left and right to loosen the side, until you hear a click, which means the screen has separated from that side. Once one side is fully released, the other sides are much easier to loosen. leave the top of the phone last, and use a guitar pick or some other shorter device to take that part off completely.

I used this tear-down to change the the lcd/glass/touch/frame assembly. I had the right tools and was very careful. But the battery gave me problems, the glue held up a good fight. I didn't know that there was a small control board in the upper part where the connector sits. So i lifted the battery all the way around, and it got a little bent while doing this. When i put everything back together, it wouldn't start. I plugged it in the charger and the LED blinks red. The battery was fully charged before i took it apart.

I suspect that i broke the battery, trying to get it out. Would you agree?

I tried to take the connector of the battery and reconnecting, no change. When i plug the charger in, while the battery is disconnected, the screen shows the battery logo. I can even turn it on for a few seconds, it vibrates and shows the google logo. then turns back off. I guess because of the missing battery?

Do you think it's safe to order a new battery, and that it will work again?

Hello , someone can help me for a problem of battery? The phone not start. I remove battery and i saw with multimeter is 2,5 volts (so is very down). Now i try to charge with a external charger (very slow for now), however on the nexus there 4 pin. Someone can tell me the right voltage when plug the usb?? Because i dont understand if the phone charge fine or not

Your writing concept is very delighted about the Iphone. That is able to compare Iphone between Macbooks, iMacs, iPads, iPhones, iPods and iPod Touches. I hope your writing concept is able to give us a useful look about the Iphone.http://www.amazon.co.uk/dp/B00FPFM4AY

While I was replacing my nexus 4 battery , I accidentally broke the white wire/cable pasted on the old battery. I could reconnect it to a certain level, but not well connected. You can see that cable is removed in Step 11 to 12 in this article.

1) What is that cable

2) I guess it is wifi antenna cable. If that is the case, is my phone un harmed given that wifi still works

3) Does it affect phone calls, I can not test it since I am out of the country where my SIM card does not work

The 4G LTE radio/modem in the Nexus 4 can be activated. You have to be rooted and have a custom recovery. A special zip file has to be flashed via custom recovery to activated 4G LTE. Google search "LTE Nexus 4 xda" open link(s) and follow directions. I got LTE on my Nexus 4 right now as I'm typing this. Oh yeah, your carrier APN needs to be corrected in settings and make sure your carrier has 4g LTE activated by default cause some, like AT&T turn LTE off when they detect you are using a non LTE phone like the Nexus 4.
